Abstract

Apparatus for supplying air or oxygen to a patient comprises an on/off valve (16 to 24) located between a gas inlet (10) and a gas outlet (28), the valve including a driving position (42) which is biased to open the valve by means of a spring (44) and to close the valve by the pressure of gas in a reservoir (34) which has a slow vent or bleed and is fed with gas from the inlet/outlet feed line (26) in accordance with the setting of an adjustable throttle (30). thus, cyclic gas supply to the patient is developed, as the valve is opened and closed in accordance with movement of the piston under the combined effect of the opposed spring pressure and gas pressure acting thereon.
